The invention relates to an'improvement infmachines for` collecting and *bundlingl articles-by wrapping and ixingfaband around a redetermined numberof the collected ar.

The object of the invention is to secure moreeilicient operation .of the-machanism disclosed.` in said patent, To this end the.

invention consists in the mechanism herein: ,after described and particularlyV pointed outin'the appended claims. 4 -Ii'rtliei accompanying drawings illustrat-y ing the preferred form of the'invention Fig.. liis a rear elevation of' so much of themachineshown and describedinsaid patentas is necessary to illustrate theapplication of the mechanism yof the present invention theretog'Fig. 2 is a side .elevat-ionpartly in` section, of Athe partsshown in Fig. 1;1 Fig. 3 is anv` enlarged side .elevation showing more 'particularly the parts constituting the 'mechanism of the present invention; and VFigff 'isa detail illustrating the mode yof operation iofithefhook device for arresting the bundlecarrier for a ypredeteririined period'during its rotation.

Y As described in said. patenti-the predeter-mined number of'articles to be gatheredw together in a compact bundle are received in i the firstA instance in'v agathering device indicated generally byl Atherec'eptacle 10 mount.-

ed onthe upper' ends/'of the bars.. 11 fas- .tened at; their lower ends on the shaft 12 'journaled' in'thef-ront of the frame 13 of the bundling machine. When vthe pocket 14 'ofthe receptacle 10. has" been filled'with4 articles -by the' feeding mechanism, generally indicated at 1'5, the active part 16 ofi the ,cam Y Y platev 17 "mounted'on the shaft V18 engages a roll Y2(1)'carried byone-arm of a'bell crank lever L22 the Vother yarm of. which is pivotal-Y connected 4with-the;ii1'i'per end of a link '24 the `lower end of-Which is connected with .an Iarm '25* extending rearwardly from the shaft 12. This action; causes the .shaft 12l the pocket to be -oscifllated slightly vto swn U' 26 into alinementwith lthe, feeding mechanism 15'. When the pocket 26 of" the receptacle 10 has been -lledwith articles and the gathered articles are'then infgcondition to be lbound into Aa compact `bundle,the pin l27 pro- 'iecting rearwardly from the cam plate 17 en.- g'ages withtheY-roll 2 8'carriedby 'one armof a bell crankV the other 29 ofi-'Which lisvpivot.-

. The tialvel ofthe carrier 54:` in the direction indicated removes the gathered'articles out'V of the open upper end of the receptacle 10., all as fully described ins'aidpatent. YThe means foi-.rotating the shaft 55 comprises a disk mounted on 'a sleeve 61 journaled on Y .the shaft 55. The lsleeve 61 is 'constantly driven 'from the sleeve 43 by the Vchain 63. On the shaft 55 is mounted an .armjf'wliich carries al dog65, the hookedv end 66 of which `is normally lheld out ofithelpathiof rotation 'ze 'i Ywith the sleeve 43, causes the cainv part `4:9 f

' of the pins 67 projecting laterally from the of which is mounted a roller 72 adapted to be engaged by a pin 7 3 fixed in the outer end of an arm 74 mounted on the shaft 87. When the shaft 37 is caused to rotate by the engagement ofthe pin 27 with the Vroller 28 the lpin 73 encounters the roller 72 and thereby oscillates the hub 70 to di sengage the arm 68 from the pin 69. Thereupon the spring 76 moves the hook-likeend 66 of the dog 65 into the path of rotation of the pins 67 to drive the shaft 55 'from the sleeve 61. As shown and described in said patent the bundie* carrier 54 makes a complete revolution and returns to its initial article-receiving position when the engagementof the arm with the pin 69 again disengages the shaft 55 from driving` connection with the sleeve 61. Y.

' During the rotation of the bundle carrier 54 the roller 80 carried by the movable jaw 81 of the carrier encounters a cam 82 formed on the end 'of a sleeve 83 secured in adjust- A bundle carrier 54 is arrested during its rotation and held stationary long enough to permit the adhesive to set, so that when the carrier is again put in ymotion and the jaw 81 actuated to release a bundle, the wrapper will remain about the bundle of articles, holding them firmly together. -.For this purpose I provide a lever 85 pivotally mounted on' the pin 93 in the lower end of a plate 86 extending downwardly from the cross-piece 87 supported on the upper ends of the rods 88 rising from the journal blocks 56. The lever 85is provided with a curved arm 89 the `lower hook-like end 90 of which is normally pressed into the path of rotation of the pin 69 of the dog 65 (when the latter has beenreleased by the arm 68) by means of a coiled spring 91 one end of which is fastened to the arm 89 and the other end of which is fixed in a collar 92 adjustably secured on the pivot pin 93. The engagement of the pin 69 by the hookedfend 90 of the arm 89 disengages the dog 65 from one of the pins 67 of the plate 60, thereby disconnecting the sleeve 61 from driving connection n On its rear side s the hub carries an arm 71 on the outer end with the shaft 55 and causing the bundle carrier 54 to stopbefore it has passed out of engagement with the arcuate guide 95 which serves to holdthe outerr fla-p of the wrapper s lso cam disk 17 and near the periphery thereof. Y

The boss 96is adapted to move into engagement with the upper end of a rod=`97 pivotally connected at its lower end'with the arm 98 of the lever 85 and mounted at its upperI end for verticatmovement on the bracket 99 which serves to support the outer end of the shaft 18 on. which the cam'disk 17 is mounted. The upper end of the rod 97 is slotted vertically at 101 to receive a screw .102 ixed in the bracket 99. Vhen the boss 96 encounters the upper offsetvr end 103 of the rodl 97 it'depresses the rod, thereby causing the lever to be oscillated in a counter-clockwise direction, viewing Figs. 3 andv 4, so as to disengage the hooked end of the arm 87 from the pin 69, as showny in 'dotted lines in Fig. 4. `Thereupon the dog 65 resumes itsconnection with oneof the pins 67 of the Vplate 60, reconnecting rthe sleeve 61 with the shaft 55 andv causing the bundlev carrieiIV to complete theremainder of its rotation, during which the securely wrapped bundle is discharged. As described in said patent, the rearwardfswing of the article receptacle 10 into discharging positiontakes place when the cam surface 104 on the cam plate 17 encounters theroller. 20. The plate 17 travels in the direction of the arrow indicated on Fig. 1. The bundle carrier 54 begins its rotation immediately after the gathered articles have been deposited into the open'jaws of the carrier bythe receptacle 10. It will be seen'therefore that the length'of time the carrier 54 is held arrested willdepend upon the position of the hooked arm 89 and the position of the boss 96 on the plate 17 When the' rotation of the plate 17 carries the boss 96 beyond the end 103 of the rod 97 the hooked end 90 ofthe arm 87 returns to normal position under the action of the spring 91.V Y A Having thus described the invention what l claim as new. is f 1.
